Abstract: The energy consumption of oilfield fuel oil heating furnaces is high, and the sulfur dioxide, nitrogen oxides and soot in the flue gas emitted seriously exceed the standard, causing serious environmental pollution. So it is urgent to replace the oilfield heating furnace. The technology principle, energy consumption calculation, equipment characteristics and feasibility of replacing oil field fuel oil heating furnace of air source heat pump and sewage source heat pump are studied, and the benefits of two heat pump technologies replacing oil field fuel oil heating furnace are analyzed. Through research, it is concluded that the air source heat pump and sewage source heat pump technology are effective ways to replace oil in the oil field heating furnace; by using air source heat pump and sewage source heat pump to replace the fuel oil heating furnace, the operating costs can be reduced by 30% and 45% respectively, and the carbon emissions can be reduced by 60% and 75% respectively. By replacing the fuel oil of the heating furnace, not only can you obtain considerable economic benefits, but you can also effectively reduce the emissions of sulfur dioxide, nitrogen oxides, and smoke.

摘要： 油田燃油加热炉能耗较高，排放的烟气中二氧化硫、氮氧化物及烟尘严重超标，对环境污染严重，油田原油加热炉替代工程刻不容缓。对空气源热泵、污水源热泵的工艺原理、能耗计算、设备特点及替代油田燃油加热炉工艺的可行性进行研究，并对两种热泵技术替代油田燃油加热炉后的效益进行分析。通过研究得出，空气源热泵和污水源热泵技术是进行油田加热炉燃油替代的有效途径；利用空气源热泵和污水源热泵替代燃油加热炉后可以分别降低运行费用30%和45%以上，分别降低碳排量60%和75%以上。通过加热炉燃油替代，不但可以获得可观的经济效益，还可以有效降低二氧化硫、氮氧化物及烟尘的排放。
